Hydrocele

Sudden, severe (acute) pain in the scrotum or testicle that lasts for more than a few minutes is an emergency. If you have this type of pain, seek medical attention right away.

A lump in the testicle is often the first sign of testicular cancer. If you find a lump, see a provider right away. Most testicular cancers are very treatable. Keep in mind that some cases of testicular cancer do not show symptoms until they reach an advanced stage.
